Of course it does -- it you want the system to behave as if you logged
in as root, use 'su - root'.  Otherwise, you get root's uid with your own
login environment -- which is what Unix su has done for as long as I can
remember, anyway.  "Unix gives you enough rope."

I believe you can also change the behavior of passwd by changing the
value of the $USER or $LOGNAME environment variables.
